Designs game server architecture for high-load scenarios, making architectural decisions documented as ADRs. Architects sharding strategies for game worlds supporting massive CCU, optimizes tick rate stability under peak load, and designs matchmaking systems that scale horizontally.

Defines architectural strategy for game server infrastructure under high load. Drives decisions on global sharding topology, cross-region matchmaking, CCU capacity models, and tick rate guarantees across the product portfolio. Mentors teams on scalable game server patterns.

Understands basic system design principles and client-server game architecture. Knows the roles of core components — game server, lobby server, matchmaking, persistence layer.

Designs server architecture for specific game modes with scalability in mind. Separates stateful and stateless components, selects appropriate state synchronization patterns.

Develops architecture for high-load game systems — game world sharding, eventual consistency for inventory, CQRS for leaderboards. Accounts for global player distribution.

Conducts architectural reviews of server systems and makes strategic technology stack decisions. Balances architectural complexity with development speed for new content.

Type Systems

▼

Understands the benefits of typing in server code and uses basic types. Annotates game event handler functions, character data structures, and inventory items.

Designs type-safe interfaces for server systems — strictly typed game events, protocol messages, API contracts. Uses generic types and discriminated unions.

Implements advanced typing for correctness guarantees — phantom types for entity IDs, branded types for validated data, end-to-end typing from protocol to storage.

Defines typing standards for the server codebase. Selects tools and approaches, ensures strict types at service boundaries, and auto-generates types from protocol schemas.

Unit Testing

▼

Writes simple unit tests for game logic — damage calculation verification, inventory validation, state machine testing. Understands arrange-act-assert structure and uses basic assert methods.

Covers server game logic with tests — matchmaking, economy, progression systems. Uses mocks to isolate from DB and network layers, applies parameterized tests for edge cases.

Builds a game server testing strategy with high coverage of critical systems. Creates frameworks for testing deterministic simulation, replay systems, and tick-based logic.

Defines testing standards for the server team — minimum coverage, mandatory load test scenarios, testing policies before every game update.
